Due to numerous applications in which this equipment can be installed, it is difficult to predict servicing intervals. In certain situations where there is heavy smoke, servicing the equipment every one two months may be needed; whereas ventilating a meeting room for example for carbon dioxide may only need service every six months to a year. Motor Access to the motor is through the front service doors. Note heat exchanger core can be removed to provide more room. See CORE in this section. The motor is a permanent split capacitor type (PSC) which uses a sleeve mechanism to steady the shaft. There is an oil wick beside the sleeve which supplies oil to it on a continuous basis. If the motor does not have oil tubes, no maintenance is required. Access to the wick is through oil tubes, (two per motor) located in the motor case itself. These oil tubes are either capped with yellow plugs, (which need to be removed for oiling) or have clear tubes protruding from them. In either case an oiling device such as an “Oil Telespout” filled with 20 S.A.E. non-detergent electric motor oil should be used to put oil inside the tubes. A couple of drops of oil once a year will do. DO NOT OVER OIL! HRV Core The heat exchange core is accessible through the front service door. Special care and attention should be given to this component as the edges may be sharp, and the core itself susceptible to damage if dropped. When removing the core, the location it is removed from should be noted. The core is removed by carefully pulling the core outward from the unit, sliding it evenly along its “H channel” supports found in each corner of the core. Note the core may have some resistance when sliding out. Avoid tilting the core as this will result in its edges catching the H channel and temporarily preventing its removal. In most cases, washing the core in a mild detergent and warm water will be all that is needed to completely clean them. Do not use harsh chemicals as this may cause corrosion in the HRV. The time between core service will depend on the application the HRV has been installed in. It can be as often as one - two months or at the very least, cleaned every six months. When reinstalling the core you must note foam location and drip edge location for proper core placement. See diagram below. Models 700, 1200 and 1000 FILTER FILTER DOUBLE DRIP EDGES DOUBLE DRIP EDGE CORE Note location and arrangement of cores and filters when removing. 21 FILTERS Open front service door to access the filters located in both supply and exhaust air streams. Note to remove and install filters, it may be easier to first remove the core(s). See CORE. The filters are designed to stop large particles from entering in the core. The filters are fastened in place by a metal spring rod. To remove filters from core(s) simply pull the rod from one end, outward until free from core lip, and remove. Only use warm water with a mild detergent to wash the filters. Do not use harsh chemicals. The time between filter service will depend on the application the HRV has been installed in. It can be as often as one - two months or at the very least, cleaned every six months. CONDENSATE DRAINS The condensate drains consist of two drain pans which may collect water after the HRV initiates a defrost cycle, and a drain line to remove the condensate. Maintenance on this portion of the system should be done as often as possible and should not exceed six months. Note bacterial growth in standing water is a major concern to healthy indoor air quality, and should be avoided whenever possible. To clean these components, open the front service door and flush the pans with water. Ensure that the pans drain completely and in a reasonable amount of time. Note if the water does not drain right away, check for blockage in the drain line, also check that the drain line has a good slope to it. (1/8 - 1/4” per foot) The drain line itself should have a “P” trap in it below the HRV which is to be filled with water to prevent odours or gases from entering back into the unit. When flushing out the drain pans, this too will be flushed out, and the water that was there will be replaced with clean water. DUCT WORK It is a good idea to inspect ducting, outside weather hoods (wall caps), and grilles for blockage and dirt buildup, at least every six months. Outside weather hoods should be protected by a rodent screen which can plug up with debris. Also, it is a good idea to visually confirm that the fresh air supply is free from any sources of contamination, such as other vented combustion equipment added after the fact. DAMPER MOTOR The damper motor, (if applicable) is a self contained motor and does not require service. The damper door attached to the motor could use a little lithium grease on the shaft opposite the motor, where it enters its holder, once every two - three years. General Maintenance As a final step in a routine maintenance schedule, it is a good idea to confirm operation of the s...
